World's Highest On-Site 3D Printed Structure

In a monumental leap for defense infrastructure and construction technology, Simpliforge Creations and IIT Hyderabad, in collaboration with Indian Army represented by Arun Krishnan (who is also a PhD student at IIT-Hyderabad), have successfully delivered India's first on-site 3D printed protective military structure at a staggering altitude of 11,000 feet above sea level in Leh under Project PRABAL.

- 

This marks the world's highest-ever in-situ 3D construction printing feat, accomplished under the extreme high altitude and low oxygen (HALO) conditions.

Under the guidance of Prof. K.V.L. Subramaniam of IIT-Hyderabad, Simpliforge Creations and IIT-Hyderabad Teams developed specialized 3D printing technology capable of operating under extreme environmental conditions. This innovation enabled the construction of a form-optimized protective bunker using locally sourced materials, completed over a total printing time of fourteen hours.

The PRABAL initiative showcases how homegrown technology and academicindustry collaboration can push the boundaries of construction science. The deployment of this 3D printed bunker is not only a first-of-its-kind in India but also sets the stage for rapid, on-site, deployable infrastructure in challenging terrains, strengthening the country's further defence preparedness.
